ABSTRACT:
A disk stacker is provided having a tamping mechanism located over a sheet receiving platform for tamping side edges of the sheets as they fall to a top of the stack. First and second vertical side registration walls are provided and positioned above a different one of two side edges of the sheet receiving platform and are spaced apart so that a sheet can be received therebetween. A first tamper is located adjacent the first side registration wall and is movable through an aperture therein between an active position wherein the first tamper extends through the aperture and is located between the first and second side registration walls to tamp incoming sheets against the second side registation wall, and an inactive position wherein the first tamper is retracted behind the first side registration wall out of an area between the first and second side registration walls. A second tamper can be provided which operates in a similar manner relative to the second side registration wall and, when the first and second tampers are alternately operated between their active and inactive positions, separate sets of sheets in the stack can be offset from each other in a direction transverse to the process direction.
